The acoustic performance of Trisomet® has been predicted using software developed by the Department of Applied Acoustics, University of Salford, under a research contract funded by the Metal Cladding and Roofing Manufacturers Association (MCRMA). The results in the table are based on an 80mm core.
|Frequency (Hz)||SRI Values (dB)*||Frequency (Hz)||SRI Values (dB)*|
* The predicted sound reduction index values should only be used to provide guidance for preliminary design and/or appraisal of cladding systems.Weighted S.R.I RW = 28.5 dB
